Embodiment 1

[0027] A plant source compound acaricide, in parts by weight, comprising 5 parts of nicotine, 2 parts of Coptidis Rhizoma extract, 3 parts of lemongrass oil, 0.1 part of pesticide fertilizer slow-release agent, 30 parts of solvent, 2 parts of cosolvent, 5 parts of emulsifier, 7 parts of dispersant, 3 parts of thickener, 1 part of antifreeze, 0.1 part of defoamer and 20 parts of water.

[0028] The solvent is ethanol, the cosolvent is n-butanol, the emulsifier is calcium dodecylbenzenesulfonate, the dispersant is sodium lignosulfonate, the thickener is sodium hydroxymethyl starch, and the The preferred antifreeze is ethylene glycol, and the defoamer is silicone oil.

[0029] Its preparation method comprises the following steps:

[0030] (1) Mix nicotine, coptis extract, lemongrass oil, pesticide fertilizer slow-release agent, solvent, co-solvent, dispersant and emulsifier together to dissolve it into a uniform oil phase;

[0031] (2) Mix water, antifreeze, thickener and defoa...

Embodiment 2

[0035] A plant source compound acaricide, in parts by weight, comprising 8 parts of nicotine, 1 part of Coptis Rhizoma extract, 2 parts of lemongrass oil, 0.3 parts of pesticide fertilizer slow-release agent, 35 parts of solvent, 3 parts of cosolvent, 6 parts of emulsifier, 5 parts of dispersant, 1 part of thickener, 2 parts of antifreeze, 0.3 part of defoamer and 25 parts of water.

[0036] The solvent is ethyl acetate, the cosolvent is n-butanol, the emulsifier is Tween-20, the dispersant is sodium lauryl sulfate, the thickener is sodium hydroxymethyl starch, the antifreeze is glycerin, and the defoamer is silicone oil.

[0037] Its preparation method is the same as Example 1.

[0038]When using, add water to dilute 100 times and spray. According to the national standard of the People's Republic of China (GB / T17980.132000), the control effect test of mites was carried out, and the control effect of apple spider mites was 95.6%, and vegetable spider mites were 93.6%.

Embodiment 3

[0040] A plant source compound acaricide, in parts by weight, comprising 10 parts of nicotine, 3 parts of Coptidis rhizome extract, 1 part of lemongrass oil, 0.5 part of pesticide fertilizer slow-release agent, 40 parts of solvent, 1 part of cosolvent, 8 parts of emulsifier, 10 parts of dispersant, 5 parts of thickener, 3 parts of antifreeze, 0.5 parts of defoamer and 30 parts of water.

[0041] The solvent is isobutanol, the cosolvent is acetone, the emulsifier is Tween 80, the dispersant is lauryl sulfuric acid, the thickener is polyvinylpyrrolidone, the antifreeze is ethylene glycol, and the defoamer is silicone oil.

[0042] Its preparation method is the same as Example 1.

[0043] When using, add water to dilute 100 times and spray. According to the national standard of the People's Republic of China (GB / T17980.132000), the control effect test of mites was carried out, and the control effect of apple spider mites was 95.6%, and vegetable spider mites were 93.6%.

Abstract

The invention relates to botanical compound miticide and a preparation method thereof; the botanical compound miticide comprises, by weight, 5-10 parts of nicotine, 1-3 parts of Chinese goldthread rhizome extract, 1-3 parts of lemon grass oil, 0.1-0.5 part of pesticide-fertilizer slow release agent, 30-40 parts of a solvent, 1-3 parts of a cosolvent, 5-8 parts of an emulsifier, 5-10 parts of a dispersant, 1-5 parts of a thickener, 1-3 parts of an anti-freezing agent, 0.1-0.5 part of a defoaming agent, and 20-30 parts of water. The on the botanical compound miticide provided herein as the advantages that after massive experimental studies and screening, nicotine, Chinese goldthread rhizome extract and lemon grass oil are compounded in a specific mass ratio to arrive at their synergy; under equal dosage, the botanical compound miticide compounded herein is better in mite-killing effect than single doses of diafenthiuron, fenbutatin oxide or chlorfenapyr; therefore, usage concentration of the botanical compound miticide can be greatly decreased, the cost is lower, lower environmental pollution is caused, and drug resistance in harmful mites can be effectively delayed.

Description

technical field [0001] The invention relates to a plant source compound acaricide and a preparation method thereof, belonging to the field of pesticides. Background technique [0002] Acarids (mites) belong to Arthropoda (Arachinida), Arachnida (Arachnida), Acari subclass (Acari). According to its economic significance, it can be divided into two categories: medical and animal husbandry acarids and agricultural pest mites. Among them, the important agricultural pest mites are concentrated in 6 families of Acariformes (Acariformes), the most important pest mite is Tetranychus mites, followed by Hypophyllus mite, Gall mite, Nematode mite and Acarid mite. Among them, spider mites are the largest group of agricultural pest mites. There are more than 200 species of 16 genera known in my country; more than 180 species of gall mites have been recorded in my country; the serious damage to nematodes includes nematodes polyphagous and rice nematodes Mites, the former harm more than 3...
